37.5mm Thread to LEE85 Adapter

This adapter ring connects lenses with a 37.5mm filter thread to the LEE85 filter holder system. It is built for photographers who want to use LEE85 filters on smaller-diameter lenses without vignetting. Precision-machined aluminium provides a secure, light-tight fit that protects the lens threads during repeated attachment and removal.

Upgrade from Step-Up Rings

Unlike generic step-up rings that only reach common thread sizes, this adapter jumps directly to the LEE85 bayonet mount. The jump is worth it when you already own LEE85 filters and holders and need a single, rigid connection instead of stacking multiple rings. It removes the flex and potential light leaks that come with chained adapters.

Handles LEE85 System Filters

The ring comfortably supports the full range of LEE85 resin and glass filters, including graduated ND and polariser sets. It runs out when a lens front element exceeds the 85mm holder width or when ultra-wide focal lengths introduce corner vignetting even with the slim adapter profile.

Questions about this item

What lens thread size does the adapter ring require to mount?

It screws onto a 37.5 mm lens thread and locks into the LEE85 filter holder system.

How is the adapter ring installed, and what step is often missed?

Screw the aluminum ring onto the 37.5 mm thread until flush, then slide the LEE85 holder onto the ring until it clicks; skipping the click leaves the holder loose.

What maintenance will the adapter ring need over time?

Wipe the threads clean with a dry cloth after sandy or salty shoots to prevent grit from jamming the 37.5 mm screw thread.
